If your car is stolen while you let it warm up, whether it would be covered by your insurance, depends on the company and your policy.

If you want to warm the car, legally, while staying warm yourself, one community in Colorado suggests investing in a remote starter. That way, the keys stay safely with you and the car remains locked but running.

Even if it is legal to warm up your car, do you really need to let the car run before heading out on the road?Mechanics say no.

The idea of letting a car warm up comes from old engines that had carburetors. Now, most vehicles don’t have the part that mixes gas and air to make vaporized fuel. Instead, the majority of vehicles built after the 1980s have fuel injection, Business Insider reported.
